I have joint physical and legal custody of my son. Visitation is set up to where I get him every Wed. and every-other weekend. I've never been late or not shown up when it was my turn to have him. I've never been late paying child support. I'm drug and alchol free and have never been in any-kind of trouble. My son is now 2 and I would love to have him a week at a time. (and then she could have him a week) My new wife has her BS degree in child development from Southeast Missouri State University and has been working with preschoolers 40 hours a week for 8 years now. There's no way my x could prove us unfit in any way. I've been at the same job for 15 years, I'm a union floorlayer in St. Louis. My x just had twins with the man she was living with from before the time our divorce was final. My new wife and I both come from good christian homes where the families are still all intact. This is my new wives first marriage and I'm the only one in my family that's ever been divorced. My x has been on felony probation for several counts of forgeryfor writting checks she had stolen from x boyfriends. She's had a dwi. I don't know if any of this matters but I hope I've given someone enough info. about my family and my x to give me some advice. Do I have a chance at winning if I try to modify our decree to where I have my son a week at a time?
